SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 554,317, dated February 11, 1896. Application filed March 4,1895. Serial No. 540,546. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH SoHwARz, a citizen of the United States, residing at Sioux Falls, in the county of Minnehaha and State of South Dakota, have invented a new and useful VVindow-Screen and Storm-Sash Look, of which the following is a specification.

My invention relates to alock which is to be used principally in securing outside window-screens and storm-sash to window-frames or for similar purposes by means of concave spring-wedges applied under a fixed staple, and the objects of my invention are, first, to provide a lock which will at all times hold the screen or sash against the blind-stop or other underlying surface; second, which look without removing from frame will successively hold window-screens and storm-sash; third,

'which without further adjustment will hold in the same opening screens and sash of varying thickness; fourth, which when not in actual use will not easily become detached, and, fifth, a lock which can be-placed in such position as will not interfere with the easy introduction or removal of sash or screens. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 shows a perspective 'of the lock; Fig. 2, a side view; Fig. 3, a top view; Fig. 4, an end view showing point of wedge; Fig. 5, an end view showing heel of wedge; Fig. 6, a view showing the application of lock to sashes or screens of varying thickness; Fig. 7, a perspective of an alternate staple which may be used in place of the one shown in the other views.

Similar letters refer to similar parts th rough out the several views.

The staple A is driven into the outside casing as far as may be necessary for the adjustment of wedge to the average thickness of sash. This staple may, if deemed desirable, be replaced bya square iron eye attached by means of screws, as shown by Fig. 7. The head B of staple is slightly concave, thereby assisting in throwing the wedge O, hereinafter mentioned, against the posts A of staple.

The concave wedge O (by wedge O is principally meant all of that part of lock referred to by letters D, E, F, G, and H, these letters only referring for better illustration to individual parts of the wedge G) is to be made of tempered material with corrugated or serrated edges, the heel D turned down and widened and made slightly concave at the base E, while the point F is turned up and slightly spread,with a depression or indentation at G, after which it is turned down and returned back to H to form a long bearing for the point of wedge. The wedge is inserted into the staple by pressing the two edges of the point F together sufficiently to overcome the slight projections above and below the indentations G and driven in between the posts A of staple until the point and heel of wedge press firmly against the stationary outside window-casing and sash or screen, re-

spectively.

As the wedge C is made slightly wider than the distance between the posts A of staple and sprung into place, the corrugated or serrated edges of wedge C are kept in close contact and engage successively in the posts A and lock the wedge (J when it has been driven in sufficiently far under the head B of staple or at any desired point. The contact of wedge Oagainst the staple-posts Ais further increased by concave form of the head B of staple. To withdraw the wedge, the heel at D and, if necessary, the point at F are pressed together sufficiently to disengage the serrated or corrugated edge of wedge C from posts A, and the wedge O is then withdrawn. When the sash or screen is to be withdrawn from the frame or casing I, the wed e O is placed in the position shown by dotted lines, Fig. 2, when the indentation G engages in the posts A of staples and holds the wedge O firmly in the upright position indicated by dotted lines, Fig. 2, whereby it in no way interferes with the introduction or removal of sash or screen.

\Vhen it is desirable to remove the wedge I O entirely from the staple, the wedge C is first placed in the position shown by dotted lines, Fig. 2. Then the points F of wedge O are pressed together sufficiently to overcome the protrudence above the indentation G, after which the wedge O can easily be withdrawn from staple. Owing to the increase in width of the point of the wedge above and below G, as also of the heel at D and E, the wedge O cannot unawarely become detached from the staple A. The constant pressure exerted by the wedge 0 against the post A of staple, owing to the slight excess of width of wedge C before introduction over distance between staple-posts A, will hold it in any desired position when not in use, and the form of the point and heel of wedge at F G 11 and D E, respectively, permit the heel and point to be pressed together without necessitating undue force.

The use of this lock, although primarily intended for the use of holding in position storm-sash and screens, is not necessarily re stricted to that purpose, but may be used advantageously under similar circumstan ces, although for different purposes.

I am not aware that a wedge and staple of this form and construction has heretofore been used for the purpose of securing window-screens and storm-sash or similar purposes, and

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The combination in storm-sash and window screen fasteners of a double spring, made of tempered wire or other suitable material having parallel corrugated or serrated edges, shaped as a wedge by turning the ends in opposite directions to form bearings, and a staple to engage the same in such manner, as to hold it in place, whether in use or not, the whole forming a device for holding in position and locking storm sash, windowscreens, or any similar structure, all substantially as set forth.
